Abstract In the disc controlling system, a buffer memory stores sector by sector data read from a disc or data to be written to the disc. A memory controller allows a floppy disc drive to intermittently read sector by sector data from the disc for supply to the buffer memory or intermittently write sector by sector to the disc data supplied from the buffer memory. When the floppy disc drive is not writing data to or reading data from the disc, data read from the disc is supplied sector by sector from the buffer memory to the system bus or data to be written to the disc is supplied sector by sector to the buffer memory from the system bus.The system can greatly reduce the load of a disk controller and a system bus.
